VAZ 2112 fuse box

If some devices on your VAZ 2112 car have stopped working, fuses or relays may be to blame. At the very least, the first thing you need to do is check them, and then draw some conclusions regarding the malfunctions. Correct diagnosis of many electrical problems will allow you to accurately determine the cause of the inoperability of a particular unit. To find out what fuses and relays do and how to find the right one, read this article.

Scheme

To replace a faulty fuse, first find the one that has blown, then eliminate the reason why it was damaged and then install a new one. Below is a list of fuses and information on each one.

Diagram and location of the VAZ-2110, VAZ-2111 and VAZ-2112 fuse box

We invite you to familiarize yourself with the diagram and location of the fuse box on the VAZ-2110, VAZ-2111 and VAZ-2112. The fuse and relay box in the VAZ-2110 is located in the car interior a little to the left and above the pedals.

This is how it looks in the interior; the main relays are marked in the photo and all the fuses on the block are numbered.

What are the VAZ 2110 fuse box relays responsible for?

Where is the cooling fan relay on the VAZ-2110

In order for everything to work correctly in the VAZ-2110 engine, it is necessary to maintain a certain temperature.
This temperature range is achieved using a cooling fan, which, as a rule, comes with an electric drive. Its activation and deactivation is carried out automatically. Moreover, if the machine contains a carburetor engine, then TM 108 is used, and in the case when an injection engine is used, a controller is used. This article will tell you where the cooling fan relay is located on a VAZ-2110 car. If the fan is controlled by switching on, it is important that the temperature setting of the housing sensor is observed. The sensor is considered faulty when its temperature has reached the switch-on level, and the cooling motor has not worked. To check, you should close the contacts of the sensor, then check whether the fan works; if so, then the sensor needs to be replaced with a new one.

There are times when closing the contacts does not help and the fan still does not work, then according to the diagram, the integrity of the fuse with the supply wires is checked.

In order to start the cooling fan of the machine in which the injection engine is located, an electronic controller is used. Temperature conditions are pre-entered into the device software and range from 100 to 105 degrees. If the temperature sensor is faulty, then a system error is selected on the controller, and the cooling fan is activated when the car engine is turned on.

A number of breakdowns occur in which the controller does not detect the breakdown, and as a result, when the required temperature reaches 105 degrees, the fan simply does not start. To perform the test, remove the temperature sensor connector while the engine is running. If the system is working properly, the sensor will start the cooling fan, and by returning the connector to its original position, the fan will turn off. In case of damage to the circuit, check the quality of the relay, fuse and underwater wires. Everything must be installed exclusively according to the diagram. To carry out express checks, they bridge terminals 30 and 87 of the fan relay, which are located in the heating shaft. To make it easier to find, look in the passenger seat area.

When the fan is activated, connect the control lamp, the housing and output 86 of the relay, then the relay will operate and the fan will start automatically. At the same time, it is necessary to manipulate such a circuit only when the relay is located in the connector block. Here it is recommended to look at the controller and the wire, the relay connector with pin 46, if there is a breakdown in one of them. If a specific click of the relay did not occur, but a positive signal goes from the main relay to pin 85, or there was a click, but the cooling fan did not start, then this indicates a breakdown of the relay and the need to replace it.

What does the second set of fuse boxes do?

The symbols F1-F20 indicated below in the electrical diagram are the elements that characterize the set of fuses. The electrical circuit in a VAZ-2110 car is protected using fuses based on the specific calculation of the model for the rated current value specified upon purchase.

At the same time, fuses are not responsible for the quality operation of the circuit consisting of a sample battery, a separate type of generator circuit, the ignition system and engine valve starting. To replace a faulty fuse in this mounting block, follow the following plan:

Find a fuse that has mechanical damage or its body has burned out;
According to the instructions, determine and eliminate the reason why it turned out to be faulty;
Install a new fuse using the backup model.

Tip: Never try to replace a fuse with special jumpers. In the future, this will lead to failure of those devices that are assigned to this fuse.

Diagram with designations for the second set of fuses in the block

All fuses are divided according to their interaction with electrical equipment as follows:

F1 (current 5A) - fuse responsible for the set of lamps that illuminate the license plate, the entire instrument panel, including the side lights and lighting in the trunk.
F2 (current 7.5A) - element that regulates the low beam on the left headlight.
F3, F4 (current 10A) - responsible for the operation of high beam in the left headlight and right fog lamp, respectively.
F5 (with a current of 30A) - is responsible for the electric window motor at the front and rear car doors.
F6 (with a current of 15A) - refers to the operation of a portable lamp.
F7 (with a current of 20A) - regulates the operation of the fan motor in the cooling system of a 16-valve engine, as well as the operation of the sound signal.
F8 (with a current of 20A) - supplies current to the heating elements located on the rear window. In addition, together with the contacts from the relay, it transmits current to the windshield.
F9 (with a current of 20A) - is responsible for the operation of the recirculation valve. It also interacts with the windshield wiper and washer sensors and headlights.
F10 (with a current of 20A) - is a backup fuse.
F11 (with a current of 5A) - regulates the operation of lamps with side lights on the starboard side.
F12 and F13 (with a current of 10A) - both fuses regulate the operation of the right headlight, responsible for the low/high beam, respectively.
F14 (current 10A) - adjusts the light from the left fog lamp.
F15 (with a current of 20A) - interacts with the electric heating of the driver and passenger seats. Protects the car from unauthorized blocking of the central locking in the trunk.
F16 (with a current of 10A) - transmits current to the breaker relay to ensure the operation of the direction indicator of the left and right headlights, and is also used to give an emergency signal (when using the emergency signal mode on the VAZ-2110).
F17 (current 7.5A) - works with the car interior lighting lamp, brake light lighting, individual lighting of the ignition system switches and regulates the operation of the trip computer.
F18 (with a current of 25A) - illuminates the glove compartment, supplies current to the heating system controllers and the cigarette lighter on the dashboard.
F19 (with a current of 10A) - is responsible for the operation of the door locks, and also informs the driver about the presence of a malfunction in the brake light lamps or side light elements.
F20 (current 7.5A) - works with the lamps of the rear pair of fog lights of the VAZ-2110.
